Supporting base product is currently widely Instrumentation ball valve used in the world, forming the casting process

Support base is a key and important part of the railway bogie truck on its product quality and performance of the railway wagon speed , overloading has an important impact . Supporting base product is currently widely used in the world, casting forming. In recent years , with rail transport to improve on overloading, high-speed requirements of the key components of the support base is also increasing performance requirements inherent product defects steel support base exists ( the mechanical properties of steel castings itself , fatigue toughness, resistance impact is not high , casting products exist unavoidable porosity , shrinkage , inclusions, cracks, etc. ) for the safe operation of high-speed rail has been a threat. Improve the overall mechanical properties of the product 's support base is a  Stainless steel needle valves  and structural adjustment of China's Ministry of Railways to resolve rail transport facing the implementation of overloading, speed , security, technology development , major issues need to be addressed to improve the effectiveness and efficiency of transportation . To ensure the safety and reliability of the rail wagons running speed , the paper creatively put  Valve manifolds  of the support base cast- forging process solutions to improve their mechanical properties. Since the original steel support base products of complex shape , casting the presence of high-gluten product support base , thin-walled structures , to bring support base increased difficulty forging casting change .
